2a, Carno Street, Liverpool, L15 4LB

2a is a detached house in Liverpool (L15 4LB). It has a recorded floor area of 52 m² (around 560 sq ft) and construction records dating it to before 1900. The latest certificate (February 2013) shows a G (score 1), near the bottom of the EPC scale. The recommended improvements would lift it to E (score 42), a 2-band jump. Main heating runs on to be used only when there is no heating/hot. The latest certificate is from February 2013, so improvements made since then won't be reflected. At 52 m² this is the 2nd smallest of 27 units on EPC record in the building, where floor areas span 51–68 m². The building's EPC ratings span G to B, with this unit at the bottom. On EPC score it ranks last in the building (1 versus a best of 89).

It hasn't traded since October 1998, a hold of 28 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £135,000 sits 350% above the 1998 sale of £29,999.
